[RESOLVED] MVC question

[Rocketdawg]

Hi All

I'm working on an MVC application and I ran into a little snag.

I've got a form with the usual textboxes and dropdowns. I decided to use jquery ajax (GET) to load the dropdowns on load (State Names & Salutations).

No matter what I try, for example:

 <AcceptVerbs(HttpVerbs.Get)> _
        Public Function ReturnSalutationDropdown() As ActionResult

            Dim dropdown As New DropDownList With {.TabIndex = 1, .DataTextField = "Value", _
                                                   .DataValueField = "Key", .ID = "ddl_coSalutation"}
            dropdown.DataTextField = "Value"
            dropdown.DataValueField = "key"
            dropdown.DataSource = AppEnumerations.BindToEnum(GetType(AppEnumerations.Salutation))
            dropdown.DataBind()
            Dim sb As New StringBuilder
            Dim tw As New IO.StringWriter(sb)
            Dim hw As New HtmlTextWriter(tw)
            dropdown.RenderControl(hw)

            Return Content(sb.ToString)

        End Function

The ID of the dropdown ends up like: ctl00$MainContent$ddl_coSalutation

It doesn't matter if I use a stringbuilder and a loop to create a <select> with <option>'s, the ID always ends up like above.

Do I have to create a javascript function to create it instead?

Thanks

Hey,

I haven't used an MVC application for a while, and I can't remember off hand, but is there not still the concept of a ClientID? This is what "ctl00$MainContent$ddl_coSalutation" is.

Hey Gep

I thought I was finally free of ClientID.

With MVC, I can use a MVC Master and the id's in the content areas are clean (the way they are written). Makes it super easy to use jquery or any other javascript library.

I was really disappointed to see the mangled id in the page source when rendering a control to string. Crap.

I read you're discussion with Motil and I guess I'll have to set the <select> in the view and simply generate the <option>s (or use another workaround)

Hey,

To be honest, this is an area that I am fuzzy on, I happened played enough with MVC 1.0, or 2.0, or that matter, or even ASP.Net 4.0, to know exactly what is going on with the ClientID. It would be interesting to hear what you find out, as I am not going to be in a position to play with this any time soon, I am stuck in SharePoint development land just now

Hey Gep

Ok, it was my bad.

I had been laying out the form before writing the ajax and I left <select id="ddl_coSalutation".... in the mark up. It was right above the target container for the returning html.

Once I removed that from the mark up, the function worked perfectly and the id was exactly as written.

BTW, I was a bit scared of MVC at first, but it's starting to get easy. Good luck on your sharepoint

Cheers

Ha ha, glad to got it sorted!

Yeah, I think I might need it
